Inferring and hijacking VPN-tunneled TCP connections

[keropiko]

Hello all,

I would like to know,  regarding this CVE-2019-14899 vulnerability,  if there is a way to apply to opnsense a fix for wireguard, similar to the fix for linux distributions with iptables

iptables -t raw -I PREROUTING ! -i wg0 -d 10.182.12.8 -m addrtype ! --src-type LOCAL -j DROP

Is there any firewall setting i could apply to my wireguard or openvpn interface?

Thank you
